the main advantages of the 5052 aluminum plate-Mingtai Aluminum

Date: 2019-11-23 09:12

Mingtai Aluminum is a large-scale aluminum sheet processing enterprise that produces 5052 aluminum sheet. The 5052 alloy aluminum sheets are representative products of 5 series products. The reason why the 5052 aluminum sheets are used in life is because the 5052 aluminum sheets have unique advantages.Next, we must know the unique characteristics of the 5052 alloy aluminum plate.




5052 aluminum plate has Strong reduction ability.

The affinity between aluminum and oxygen is very strong. 5052 aluminum is easily oxidized in air to form dense and strong A1203 film with a film thickness of about 0.1μm. The melting point of A1203 is as high as 2050°C, which is much higher than the melting point of aluminum and alloy aluminum plate. One 600 °C). During the soldering process, the oxide film hinders good bonding between the metals and is liable to cause slag inclusion. The aluminum oxide film also adsorbs moisture, which causes the weld to create pores during welding.

5052 aluminum plate has Higher thermal conductivity 

The thermal conductivity and specific heat capacity of aluminum and 5052 aluminum plate are more than twice that of carbon steel and low alloy steel. During the welding process, a large amount of heat is quickly transferred to the interior of the base metal, so the heat is removed when welding aluminum and alloy aluminum plates. Consumed in molten metal, more unnecessary consumption in other parts of the metal.

The tendency of hot cracking is large.

Aluminum and alloy aluminum sheets have a coefficient of linear expansion that is approximately twice that of carbon steel and low alloy steel. The volume shrinkage of aluminum during solidification is large, up to 6.5%, and iron is 3.5%. Therefore, aluminum and alloy 5052 aluminum plates are prone to shrinkage, shrinkage, hot cracking and high internal stress during welding.

5052 aluminum plate has High stomatal sensitivity.

Aluminum and alloy aluminum plate liquid molten pool can easily absorb hydrogen and other gases. A large amount of gas dissolved at high temperature can not be precipitated during cooling and solidification after welding, and pores will be formed when gathered in the weld. The moisture in the arc column atmosphere, the welding material and the moisture adsorbed by the oxide film on the surface of the base metal are all important sources of hydrogen in the weld.
